Simpson, prices are all over the map depending on % of finish, serial number, was it an army, navy, marine issue, and on and on. Also if there was any documentation, or a confirmed story with the pistol, etc. There were 1,643,000 plus made just by Colt alone refered to as WW2 Military variation (I think). I recommend "Blue Book of Gun Values" by S P Fjestad. It can point you in the right direction, and it is a nice book to have anyway. The book is a big help for serial number searches for year made.
